<DD>CMYK pixel format.  Unlike RGB, which is an additive color model used
 primarily for display, CMYK (Cyan/Magenta/Yellow/Key) is a subtractive
 color model used primarily for printing.  In the CMYK color model, the
 value of each color component typically corresponds to an amount of cyan,
 magenta, yellow, or black ink that is applied to a white background.  In
 order to convert between CMYK and RGB, it is necessary to use a color
 management system (CMS.)  A CMS will attempt to map colors within the
 printer's gamut to perceptually similar colors in the display's gamut and
 vice versa, but the mapping is typically not 1:1 or reversible, nor can it
 be defined with a simple formula.  Thus, such a conversion is out of scope
 for a codec library.  However, the TurboJPEG API allows for compressing
 CMYK pixels into a YCCK JPEG image (see <A HREF="../../../org/libjpegturbo/turbojpeg/TJ.html#CS_YCCK"><CODE>CS_YCCK</CODE></A>) and
 decompressing YCCK JPEG images into CMYK pixels.

 component represents the black & white portion of the original image, and
 the Cb and Cr (chrominance) components represent the color portion of the
 original image.  Originally, the analog equivalent of this transformation
 allowed the same signal to drive both black & white and color televisions,
 but JPEG images use YCbCr primarily because it allows the color data to be
 optionally subsampled for the purposes of reducing bandwidth or disk
 space.  YCbCr is the most common JPEG colorspace, and YCbCr JPEG images
 can be compressed from and decompressed to any of the extended RGB pixel
 formats or grayscale, or they can be decompressed to YUV planar images.
